Roaring Judy Fish Hatchery

Water Supply

The fish hatchery meets its water needs by diverting from the East River along
with 2 springs and 6 wells with water rights totaling about 45 cfs (29 MGD).
These sources provide for average daily usage ranging from 15 MGO (23 cfs) in
the winter mOrlths to 27 MGD (42 cfs) in June. Approximately 75 percent of the
water used is from surface sourCt~s. This use is considered a non-consumptive
use of water. A few residence, on the property get potable water frc,m the wells.
No treatment of the water is currently performed, but plans are to begin treating
water from the west spring with ultraviolet to control whirling disease and other
problems.

A limiting factOr for the hatchery is the amount of water available from the wells
in the winter. The well water is warm and is mixed with cold surface water in
winter to reach an optimum temperature for fish culture. Also, well water is low
in dissolved oxygen, whereas river water is higher in dissolved oxygen. Well
pumping gener,ally occurs from September through May.

Wastewater

Wastewater is discharged from the hatchery through two connected settling
ponds. Generally, effluent settleable solids are lower than the influent settleable
solids.
